Earth science is the Branch of Science. In earth science we mainly know about the Galaxy, Stars, etc But in the History of Earth Science the name Earth Science come from Atmosphere, Water, Volcanoes, Earthquakes, etc. In the Study of the Earth Science Many Scientists Discover that when and how the ocean formed, Rivers formed, How the Earthquakes comes and how the Present Future and the Past Evolution of the Earth occurred. Many Scientists Research many types of Researches about the Earth Science and Continuously they Research about the Earth.
There are Mainly Four Branches of this Science that are- Geology, Meteorology, Oceanography and Astronomy. Now we were this Branches in Brief :-
Geology :- Geology is the study of the Earth, the structure of the Earth, the processes on the earth, History and future of the Earth. Geologist also research about the Fuels, Minerals, and the hazards on the earth and study about how to protect the Earth from the hazards. Geologist word comes from the word Geology means Geo+Logist the study of Earth.
Meteorology :- Meteorology means the study of Atmosphere, the changes in the atmosphere and the hazards in the atmosphere. In simple words we can say that Meteorology is the study of Weather and the Climate. Many times if any places there is a situation of Tsunami, Floods, etc then Meteorologist study about the atmosphere and give a way to save peoples from the hazard.
Oceanography :- Oceanography is the Study of the Earths Oceans and their Movements, their compositions, Structures, Lengths and Hazards and their Organisms. The Scientists Maintain the Oceans, protect the peoples from hazards.
Astronomy :- The study celestial bodies like Universe, Galaxies, Asteroids, Comets and Nebulae is called Astronomy. The Study of Astronomy is very important because without the study of universe we couldn’t Know about the sun, moon, stars, planets, galaxies, etc.
